Open-source alternatives to Terraform
Compare community-driven replacements for Terraform in infrastructure as code (iac) workflows. We curate active, self-hostable options with transparent licensing so you can evaluate the right fit quickly.
Terraform
Terraform is an open-source infrastructure-as-code tool that lets you define cloud and on-premises infrastructure resources in human-readable configuration files. It supports many providers (AWS, Azure, GCP, Kubernetes, etc.) through plugins, enabling a unified way to manage diverse resources. Using Terraform, teams can version control their infrastructure, preview changes (execution plans), and apply updates consistently. It handles resource dependencies and state management, allowing safe creation, change, and destruction of complex environments with a single command, thus automating infrastructure provisioning and reducing manual errors.Read more

Choosing a infrastructure as code (iac) alternative
Teams replacing Terraform in infrastructure as code (iac) workflows typically weigh self-hosting needs, integration coverage, and licensing obligations.
- 3 options are actively maintained with recent commits.
Tip: shortlist one hosted and one self-hosted option so stakeholders can compare trade-offs before migrating away from Terraform.
